PURPOSE:To process whole memory areas until they are utilized completely and to improve the using efficiency of the memory by assigning a required area at the time of requiring the memory without previously assigning a memory area. CONSTITUTION:The contents of an address converting memory 7 are read out by address signals 1, 3 outputted from a CPU6 and a writing signal 11 is kept at ON status. When a block is not assigned to a main memory 8, the contents of the signal 11 and counter 9 are written in the address of a memory 7 as the addresses of the memory 8 by a signal 1 or the like and a new block is assigned. SInce the memory 7 forms automatically a real address of the memory 8 by using the counted value of a counter 9, normal processing can be attained without assigning to any memory until the memory 8 is used completely. Thus, the using efficiency of memories can be improved. |
